Michigan University Researchers Developed Cardiac Pacemakers to be charged due to human body motion

Michigan-University-Cardiac-pacemakers-batteryCardiac pacemakers save many lives but have batteries with short time life.

For this reason researchers have been looking for ways to avoid costly and invasive battery replacement surgery which is currently performed on a patient every 5 to 10 years.

EurekAlert reports that researchers from the Michigan University have developed blueprints for heart powered pacemakers using a ceramic layer that expands and contracts to generate enough energy that it might one day eliminate battery replacement surgery.

From electricity generating sneakers to piezoelectric backpacks, the idea of harnessing human motion to generate electricity has been much hyped. But there can be fewer more elegant, and more important, uses than to harness the own rhythms of body in order to help keep those rhythms going.

Researchers Karami and Daniel Inman, chair of Aerospace Engineering at Michigan University developed a device could generate 10 microwatts of power, which means about eight times the amount a pacemaker needs to operate performing heart rates from 7 to 700 beats per minute.
